operating mechanism. Fig. 2 is a rear elevation thereof, and Fig 3 is a plan of the same.

Thisinvention consists in an improved mode of operating the plows or cultivator-teeth, whereby all the plows may be elevated and lowered simultaneously, or those on either side alone, the necessity of the operator calling his hands into requisition being dispensed with, and novel means provided for suspending said plows at a suitable height when the machine is passing over ground not to be cultivated, as will be hereinafter fully explained.

To enable others skilled in the art to which my invention appertains to fully understand and use the same, I will proceed to describe its construction and operation.

In the accompanying drawings, A A represent the carrying-wheels, which are journaled upon the lower horizontal ends of crooked axles B B, rigidly fastened in the ends of the main axle O. This method of mounting the wheels is adopted for the purpose of elevating the axle G (which constitutes part of the framing of the machine) to the required height without increasing the diameters of the wheels.

D represents the tongue, which 'is-bolted or otherwise securely fastened to the cross-pieces E E, and instead of extending to the axle O and being attached'thereto, as is usually the case, projects but a very short distance from the foremost part of the machine, so as to present an unobstructed view of the plants to the driver from his seat 13. This seat 13 is mounted upon the rear ends of hounds G G, which converge toward the front of the machine, where theyare fastened to the uprights H H-by screws, bolts, or otherwise. To the lower ends of these uprights H H the front ends of plow-beams I I e attached by means of universal joints 13. shown in Fig. 1.)

J represents the cultivator-teeth J of which'are rigidly attached tr beams I in any suitable manner.

K K are uprights rising from beams I, passing through metallic the axle (J, and designed to keep tor-teeth J in the proper vertical pc the machine is in operation by m It It resting upon said metallic lor I} represents a transverse bar tached to the uprights K K by b through corresponding orifices i The bar L may be provided with these orifices, so as to permit the: tal adjustment of the lower end rights KK. The upper ends are a zontally, so as to preserve the cor of the plows by being shifted fron of the loops 7a 70, where they are ls by the pins k W.

M represents an upright, to ti of which is affixed a shield, M.

N N represent treadles of pecul tion, suspended from a transvei and pivoted to lugs n n, rigidly aft N is a short arm or leverforme of the treadles N, and situated at therewith.- To the end of the ar tached a rod, 1?, which is connecter end to the shanks J, or to the which said shanks are secured, b; staple, Q. The hooked ends a treadles not only afford conveui the feet of the driver, but by tllt abled to elevate a portion or all vator-teeth when they meet ob passing through the soil, and also teeth at a sufficient height abovr by simply depressing the ends a ing them to the staples Q, as sho outline in Fig. 1.

R B may represent levers pivr the hounds G G, and passing th lic loops S S upon the uprights K levers the driver is enabled to thr from side to side with great facili prevent them from uprootin g any may be out of line.

The above machine is well a used in connection with suitable s anism, as illustrated in Fig. 3.

T represents a hopper support hine upon the plow-beams. preference provided with a r, U, r otated by a pulley, V, from an ordinary band run- I: pulley, W, formed upon the of the machine will be readom the preceding description. it cultivator-frames have be d to be raised separately or l or foot levers and retained position. This, therefore, I Ia-im. escribed my invention what I claim as new therein, and desire to secure by Letters Patent, is-

In combination, with the pivoted cultivatorframes I J J K L, the hooked foot-levers N N n, rods P, and staples Q, all constructed,
